PAINT OR VARNISH REMOVER.

. No Drawing.

To all whom it may concern Be it known that I, CARLETON Ennis, a citizenof the United States, and resident of White Plains, in the county ofVest chester and State of New York, have made certain new and usefulInventions Relating to Paint or Varnish Removers, of which the followingis a specification.

This invention relates to paint or varnish removers and relatesespecially to removers comprising chlorinated or other compounds havingan acid forming tendency in which antacid materials are used to obviateor correct such tendency.

Chlorinated organic solvents, such as carbon tetrachlorid, are desirableas ingredients for paint or varnish removers because reducing ordestroying their inflammable character. Such remover ingredients, whichinclude chl g r l z ol and some cases have an acid formi g cy, that is,have either acid properties or have a tendency to form in connectionwith the alcoholic and other remover ingredients bodies of an acidcharacter whichv are undesirable, as is also sometimes the case withother esterification products containing chlorin or other acid radicals.Antacid material is therefore desirable to prevent or neutralize suchacid tendency in the remover and may comprise inorganic neutralizingmaterial, such, for example, as zinc oxid, calcium oxid or magnesiumoxid, preferabl ili tlie liglit levigated or pi eeipitated form. Organicantacid neutralizing material is, however, preferable, since it is morecertainly and thoroughly incorporated throughout the entire remover, asWell as being somewhat more desirable in its action, a gil in, 939a, anddiarnin gz ene being desirable organic bodie this character. Otherantacid material which seems to prevent or retard the acid tendency inremovers of this character may comprise aromatic organic bodies, such asmegthol, ter iineol, methyl )rotocatechuic ald eliyde, safiiol,

eo1',mu1 1and other salicylates, geran cltronellol. One or more of suchantacid agents may be used in removers in connection with suitableloosening finish solvent material, that is, solvent material having agenerally alcoholic character or action in removers, such, for example,as

In addition tothe chlorinated hydrocarbon solvents referred to, other pene tratingfinish solvent material, that is, solvent material having a generallybenzolic character for action in removers, may also be used, such asbenzol, toluol, ,x 01, cum ene, benzin and i ai 'ious other pe claimhydrocarbons and m otl e ethers and other este'r c compounds. Althoughnot necessary in all cases suitable stiffening materiau may be employed,such wood flour, starch, whiting, infusorial this character, such aszinc, calcium or maglfisillm oXid and also lilin-forming stiffen ingmaterial may be used, such as nitratedeellulose and other solid organicbodies having the property of forming an evaporation retarding film overthe remover surface when in use. All the ingredients are preferablythoroughly incorporated by agitation at the desired slight increase oftemperature, the soapy, waxy or other film-forming stiffening materialbeing preferably first dissolved in the more energetic solvents,although not necessarily so compounded. An illustrative remover of thischaracter may comprise carbon-tetrachlorid 40 gallons, denatured alcohol55 gallons, pgresin w g 20 pounds, anilin 10 pounds ihtldig ht magnesia10 pounds. Another illustrative remover may comprise carbon-tetrachlorid60 gallons, ethyl alco- 1101 35 gallons, ceresin wax 25 pounds and lightmagnesia 10 pounds. Another desirable remover may comprisecarbontetrachlorid 50 gallons, light oil of hard wood tar 40 gallons,ceresin wax 25 pounds, wood flour 50 pounds, zinc oxid 10 pounds, urea 5pounds, citronellol 5 pounds.

Another illustrative remover may comprise chlorbenzene 40 gallons,carbon-tetrachlorid 15 gallons, denatured alcohol 25 gallons,

amyl acetate 5 gallons, methyl acetate 10 gallons, light magnesia 20pounds and parafiin or ceresin wax 10 pounds, although, of course, thefilm-forming stilfening ma terials may be omitted in these removers whendesired.
